'99 5 speed trans oil change, why not fill to overflow? why -11mm??

[Boxstard]

Input shaft has an oil seal so overfill won’t immediately cause leakage and wet clutch…. But regardless it is specified for reason, and I trust Porsche engineers know how fluid sloshes around when the car is in motion… not logical reason to fill to the plug hole.

Because the 5-spd tranny is from Audi, the hole location was not originally designed for Boxster installation thus the height spec., I guess…. It’s not a big deal to check it, if you can bend and mark a paper clip. Can be done faster than typing up a question here.

Ok, this is exactly why I asked. The hole position was not originally placed for this exact set up.

I will DEFINTELY do the -11mm from the hole.
I'll add the 2.25l and check from there.

Thank you everyone for your inputs :0)

Interestingly the 6 speed is filled to overflow so I suspect they put the fill hole in the right place.

Right, Audi did not design it obviously…
